Abstract

The invention provides a sonde pay-off rack. The sonde pay-off rack comprises a connecting rack, a winding wheel and a speed reduction retaining block and is characterized in that the connecting rackis provided with at least one fixing shaft; the winding wheel sleeves one fixing shaft and rotates by using the fixing shaft as the axis; the speed reduction retaining block is connected with the connecting rack, and the speed reduction retaining block contacts with the winding wheel and provides resistance to reduce the rotation speed of the winding wheel. The sonde pay-off rack has the advantages that cable storage and pay-off are achieved through the winding wheel, pay-off speed is controlled through the speed reduction retaining block, and the pay-off rack is high in automation level, compact and reasonable in structure, convenient to operate, less prone to release fault generation and applicable to various meteorological environments.

Description

technical field [0001] The invention relates to the field of equipment accessories, in particular to a radiosonde pay-off stand suitable for the release process of a spherical radiosonde. Background technique [0002] In meteorological operations, radiosondes are commonly used for meteorological detection such as high-altitude temperature, humidity, pressure, and wind. The conventional radiosonde is carried into the air by a radiosonde, and the balloon and radiosonde are connected by a rope, usually 30m long, to ensure that the radiosonde’s measurement of temperature and humidity is not affected by balloon radiation and wake. The release of the balloon is usually done by professionals. Before the release, it is necessary to manually control the release speed of the rope. First, the balloon and the rope are slowly lifted into the air, and the end of the rope is grasped by hand before releasing the radiosonde. It is also necessary to prevent accidents of the radiosonde. Falli...
